Kazzem Jalali, a member of the Iranian Majlis (parliament) National Security and Foreign Policy Commission, said "This claim is unreal because the 20-percent enriched uranium is needed for Tehran's (research) reactor and its medical purposes," according to the report.

On Saturday, some Western media quoted Mohammad Hassan Asafari, another member of Iran's Majlis National Security and Foreign Policy Commission, as saying that as a sign of "goodwill" in negotiations over the country's nuclear program, Iran has already suspended its 20-percent nuclear enrichment.

Jalali stressed that "In line with defending our nuclear rights, we believe that uranium enrichment is our inalienable right."

Meanwhile, an informed source told Fars Sunday that "20-percent uranium enrichment activities continue as before and no change has happened."

The West has been accusing Iran of secretly developing nuclear weapons under a civilian disguise, a charge that has always been denied by Tehran.
